SPECIFICATION forming part of Letters Patent No. 373,963, dated November 29, 1887.

Application filed December 2, 1878. i

To aZZ whom it may concern: Be it known that I, MARTIN BRUNER, Jr., a citizen of the United States, residing at Buckland, in the county of Auglaize and State of Ohio, and formerly aresident of Fremont, in the county of Sandusky and State of Ohio, have invented a new and useful Improvement in Cultivators, of which the followingis so full, clear, and exact a description as will enable others skilled in the art to which my invention appertains to make and usethe same, reference being bad to the accompanying drawings, in which Figure l is a longitudinal section of my improved cultivator. Fig. 2 is a rear plan view of the same. Fig. 3 is a detail View of the shovels and their connecting mechanism. Fig. 4 is a side elevation of the cultivator, showing in full lines the shovels adjusted in position to plow the ground and in dotted lines the shovels as adj usted up out of contact with the earth. Fig. 5 is a similar view, but showing the plows as adjusted up out of contact with the earth in full lines.

This invention relates to cultivators; audit consists in the novel construction, combination, and arrangement of parts; as will be hereinafter fully described, and particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, the main frame of the cultivator is designated by the reference-letter A. This frame is suitably mounted on the axle B by eyebolts b b, which embrace the axle, and by the tie-rods O (l, which are secured to the ends of the axles, and which extend up'and forward and are secured to the cultivator-frame about midway between. the axle and the point where the pivotal plow:

beams are secured-to the mainframe through the medium of the pivotal bearings and the supports a a.

The axle B is bent at each end at about right angles to the line of the main portion of the axle, and at their outer ends they are bent a second time to form the arms 0 c, which arms also serve as the axle-bearings for the wheels D. D.

Above the main central portion of the axle B are pivotally secured the rods E E, which are made in the shape of an inverted and elongated U, and are pivotally secured at their ends to the main frame of the cultivator A. At their upper central portion they support the vertical standards F F, which are pivotally secured to the rods E E at f f, and at g g to the plow-beams G, and are free to vibrate back and forth and vertically with the rods E E when it is desired to raise or lower the plows and plow-beams of the cultivator. These standards are also adapted to swing from their pivotal points ff on the rods E E to move the plow-beams vertically and laterally or from side to side, to bring the shovels any desired distance from the row when it is straddled by the machine, and to enable the operator at will to dodge irregular hills or obstructions. At the lower ends of the vertical standards F F, by means of a bolt, 9 9, pass ing through the standards and plow-beams, are pivotally secu red the plow-beams GG. These plow-beams G G are also pivotally secured at their front ends to the main frame A at the points a a through the medium of the curved I metal arms H H, which are rigidly secured to the forward ends of the plow-beams. To the main beams G G, I attach shovel-beams H H, to which are secured the knees D D. These knees are encircled at their lower ends by lips jj, which are on the back of the semicircular shovel J.

The knees D D are made of metal, and should be slightly elastic, and I find in practice that the best metal of which to make them is steel. These metallic knees D D are adapted to slip over or embrace the shovel-beams H H, and are rounded or curved together at their lower ends to receive the lips j j on the shovel J. At (2 these knees D D are pivotally secured to the shovel-beams H H. Somewhat above the pivotal point 01 is a perforation, e, which registers with a corresponding perforation in the shovel-beams H, which perforations are adapted to receive awooden pin, 6, which will break and prevent-the accidental breaking of the shovels or shovel-beams should .the plows strike against a stone or root orany other rigid obstruction.

The lips j j are perforated to receive a bolt,

k, which extends through the perforations in the lips, and serves as a means of rigidly securing the shovel J to the lowerportion of the knees D D.

The shovels proper are adapted to be adjusted to throw the dirt in or out, as may be desired. They are also adjustable vertically, so that they may be arranged to run at different depths in the same cultivator when it is desired. The shovels proper are formed with a pointed end, K, while the opposite end is cut on a diagonal slant, L, and the shovels are reversible on the knees I) D, above described.

In the lower forward part of the cultivator I provide shields M M, which are mounted on rods U N,which rods are secured at their upper ends to the main bcamsG G. It will also be observed that the plow beams are so mounted and supported with their pivotal connections that as the upright standard F is thrown forward the line of the strain at the pivotal point of support f is thrown out of alignment with thelower pivotal pointot'support of the rods E E, and forward between this lower pivotal point of support of the rods E E and the pivotal point a on the main frame A, which will cause the standard to rest on the axle, where it will be held by gravity until the standard is pulled back at its top a sufficient distance to bring the line of the strain on the point of snpportf into alignment with or back of the pivotal point of support of the rods E E, and between them and the pointy on the beam G, when it will drop down.

The rear ends, A A", of the main frame A are provided with a seat, B',which is mounted on a spring extending across from one side of the frame to the other and supporting the seat in a central position on the cultivator.

Each of the vertical standards F F and the plow-beams proper are provided with a stirrup, O O, which is adapted to receive the op' erators foot, and through the medium of which the operator may press the plows on either side deep into the earth, either together or independently, and also easily and readily move the beams and plows to and from the row, as the beams swing freely from side to side, as they are supported by the pivotal bearings ff on the uprightstandards F F and the pivotal points a a on the main frame A A, giving great leverage and power to the operator, and keeping the faces of the shovels straight to the front, which cannot be accomplished in any other manner.

The upper portions of the vertical standards F F are provided with cables P,.whicl1 are secured to the standards at one end, and which are secured to a spring, R, at their lower forward ends, which spring is in turn secured to the main frame A. These springs and cables will operate to assist the operator in steadying and in the forward movement of the vertical standards F F; also in making the shovels run at any desired depth and in making the lateral movement of the beams easy, at the same time relieving the draft by transferring the weight of the beams and shovels direct to the wheels.

From the foregoing it will be observed that each of the plow-beams G is supported by an independent standard, E, which slandard is adapted to be raised or lowered by tilting the rods E backward or forward.

The plows of either side of the cultivator may be raised or moved sidewise to clear a stump or stone or any obstacle or irregular hill or plant in the path of the cultivator which it is desired to clear in passing over, or both plow-beams and all oftheshovels may be raised. by simply tilting the vertical standards F forward when it is desired to raise all of the plows out of the ground to clear any obstacle, or to throw the plows up out of the way when it is desired to go to and from the fields or anywhere over the road.

Having now fully described the construction, arrangement, and advantages of my cultivator, what I desire to secure by Letters Iatout, and what I therefore claim, is-

1. In a cultivator of the character described, the frame, the two independentiy-rocking V01 tical standards, and pivotal rods pivoted to the cultivator and to the standards above the axle,

in combination with the plow-beams, substantially as described.

2. In a cultivatorofthe character described, a frame carrying two indepcndently-ad justable plow-beams having vertical standards pivoted thereto, and pivotal rods secured to the cultivator and also to said standards, in combination with cables provided with springs for the standards, substantially as described.

3. In a cultivator of the character described, a main frame provided with rods pivoted there to, in combination with two independentlyadjustable plow-beams having vertical standards pivoted thereto and pivoted to said rods on the frame above the line of the frame, and also pivoted to the plow-beams back ofthe pivotal point of support of the said pivotal rods, substantially as described, whereby when the plow-beams are raised the standards pass the pivotal points of the rods and are locked in position, substantially as and for the purposes specified.

In testimony that I claim the above as my invention I hereunto set my hand in the presence of two subscribing witnesses.
